Generator Protection Relay

BEPR-560U Generator Protection Device

(Suitable for the generator from 10MW to 100MW)

Description

BEPR-560U generator protection device is designed specifically for small sized generators.

The device has the following features:

Product Feature and Benefits

• USES the international most popular fast processors, frequency is 166 MHz, the built-in rich resources, simple peripheral circuit design, ensure the manufacturing quality and stability of the product. Sufficient hardware resources, 4 MB Flash Memory storage, 8 MB SDRAM.
• Measure three phase current (Ia, Ib, Ic), three phase voltage (Uan, Ubn, Ucn), active power P and reactive power Q, power factor cos phi, frequency F.
• Most 10 road  input intake interface which users can customize name.
• Protection components's outlet style by trip matrix setting, convenient for users to choose to the action of the relay. All relay output interface can choose for the tripping contact (to be automatic return) or signal contact (return back).
• Oneself take operation can be adaptive 0.5 A ~ 5 A jump switching current switch.
• The style of GPS clock Correction time uses hard contact points of pulse pair.
• Differential protection is a criterion to prevent the equipment start or outside a failure of the criterion of TA saturation cause the differential protection misoperation.
• Effective and reliable criterion PT wire break, effectively prevent the  motor's low voltage components misoperation.
• 100 M Ethernet communication interface, supports IEC60870-5-103 specifications.
• 9 of the fault wave record, each wave record contains 1.9 seconds sample point and amplitude wave record, the sampling point wave record largest contains 14  road simulation (interval is 1 ms), amplitude wave record largest contains 40  analog amplitude and 32 switch for 5 ms (interval). Article 2 the motor start wave record (interval is 100 ms), before the start of the 1 s, started 29 s.
• Using the graphical programming technology, as well as a stable and reliable protection relay library, improve the reliability and validity of the program.
• The machine static low power consumption (about 6 w), LCD module to adopt new technology, life is greatly improved.
• High anti-jamming performance, through 10 emc certification testing, transient, electrostatic discharge, surge anti-jamming performance achieves the highest grade (grade Ⅳ) standard.
• working environment temperature range: 25 ℃ ~ + 55 ℃ (LCD no vague, dull phenomenon).
